Hello, I'm searching for some advice and such on the White Mage job for PvP.

I'm still quite the novice on the matter of PvP. But it's a great way to unwind from raiding and more. So hence I'm trying to improve as a White Mage. However I received little to no information from friends who PvP as they don't play White Mage. So here I am, asking for advice on the job.
